⚠️ IMPORTANT BUYING NOTICE:

• CD03XL Internal Slim-Chassis Layout Blueprint: This professional-grade 11.40V Lithium-Polymer (Li-Polymer) internal replacement battery pack features a specialized thin-profile layout measuring exactly 185.10 x 103.70 x 8.30 mm and weighing an agile 226.00 g. It seats securely flat into your laptop's designated internal chassis tray alignment guides without generating structural pressure against the lower baseplate panel, preventing palm rest warps or mechanical trackpad click stiffness.

• Model Generation & Series Verification (Crucial Rule): This high-efficiency power engine is custom-built exclusively for the fourth and fifth-generation HP ProBook 640 G4/G5, ProBook 645 G4, and ProBook 650 G4/G5 enterprise notebook series. Please note that it will not fit older ProBook platforms (such as the ProBook G0, G1, G2, or G3 generations which use external cylindrical sticks like the CA06 profile), nor will it fit later redesigned systems (such as the G7 or G8 lines). Those alternative iterations utilize completely different internal physical dimensions, non-matching screw alignment tabs, alternative terminal connection layouts, and alternative voltage matrices. Before completing your checkout order, unscrew your notebook's lower base cover plate to physically verify that your stock factory battery explicitly features tracking part numbers like CD03XL, CD03, HSTNN-LB8F, or 931702-421.
